Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 117.15 g/mol gives 3-Amino-3-methylbutanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Amino-3-methylbutanoic acid (CAS 625-05-8) is a high-purity analytical reference standard with the molecular formula C5H11NO2 and a molecular weight of 117.15 g/mol.
The molecular framework of 3-Amino-3-methylbutanoic acid (C5H11NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Amino-3-methylbutanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
